Waste heat boiler—a device that uses waste heat from a process to produce steam, p. 297. Water tube boiler—a type of boiler that contains water-filled tubes that allow water to circulate through a heated firebox, p. 296. 14.1 Introduction Steam has many applications and a long history in the process industries. Steam provides
Jan 29, 2021 · A waste heat boiler uses the heat formed as a byproduct of another process, heat which would normally be wasted, and uses it to create steam. The steam can be used to drive turbines which produce electricity. Alternatively, the boiler can simply be used to heat water or other kinds of fluid.
(1) Natural circulation waste heat boiler: the flue gas is the tube cluster in the horizontal direction that flows through the vertical direction. The density difference between the water vapor mixture in the tube and the cold water in the tube is the motive force to maintain the natural circulation of the steam water mixture in the evaporator. (2) Forced circulation waste heat boiler: …
Waste-heat boilers rely mainly upon convection for heat transfer. For high rates of transfer, gas velocity and draught loss are both high. Consequently an I.D. fan is usually installed with a waste-heat boiler. 2. Heat in Steam Produced
Waste heat boilers utilise the heat in flue gases from combustion processes or hot waste air flows from industrial processes to generate hot water or saturated steam. Due to economic and legislative considerations, waste heat boilers are frequently used in conjunction with gas turbines and combined heat and power units. The impact of rising energy costs, however, has also led to increased use of waste heat boilers to exploit the waste heat …
CLASSIFICATION ACCORDING TO PURPOSE According to application of waste heat boilers: If the application is such that the end user needs a thermal oxidizer system for pollution control and also has a need for steam, adding a Waste Heat Boiler to the thermal oxidizer system is a very effective way to recover energy that would otherwise be discharged to atmosphere.
